TimeSpanScaleOptions.GridAlignment Property

Gets or sets the time-span measure unit to which the beginning of an axis’ gridlines and labels should be aligned.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.dll

NuGet Package: DevExpress.Charts

Declaration

[NonTestableProperty]
[XtraSerializableProperty]
public TimeSpanGridAlignment GridAlignment { get; set; }

Property Value

Type Description
TimeSpanGridAlignment

A value that represents the measurement unit to which the beginning of an axis’s gridlines and labels should be aligned.

Available values:

Name Description
Millisecond

Specifies millisecond as the time-span unit to which axis grid lines should be aligned.

Second

Specifies second as the time-span unit to which axis grid lines should be aligned.

Minute

Specifies minute as the time-span unit to which axis grid lines should be aligned.

Hour

Specifies hour as the time-span unit to which axis grid lines should be aligned.

Day

Specifies day as the time-span unit to which axis grid lines should be aligned.

Property Paths

You can access this nested property as listed below:

Object Type Path to GridAlignment
AxisBase
.TimeSpanScaleOptions .GridAlignment

Remarks

This property is available when the SeriesBase.ArgumentScaleType or SeriesBase.ValueScaleType property is set to TimeSpan, and the ScaleOptionsBase.ScaleMode property is set to Manual.

GridAlignment=Hour , MeasureUnit=Hour GridAlignment=Day , MeasureUnit=Hour

To maintain time-span values at different detail levels, use the DateTimeScaleOptions.MeasureUnit property.

To change the step interval for grid lines and axis labels, specify the ScaleGridOptionsBase.GridSpacing property.

Example

The following example shows how to group minute-by-minute data into data points with a greater measurement unit (“Hour”).

To do this, you can use the following code:

private void Form1_Load(object sender, EventArgs e) {
    XYDiagram diagram = chartControl1.Diagram as XYDiagram;
    if (diagram != null) {
        diagram.AxisX.TimeSpanScaleOptions.ScaleMode = ScaleMode.Manual;
        diagram.AxisX.TimeSpanScaleOptions.MeasureUnit = TimeSpanMeasureUnit.Hour;
        diagram.AxisX.TimeSpanScaleOptions.AggregateFunction = AggregateFunction.Average;
        diagram.AxisX.TimeSpanScaleOptions.GridSpacing = 6;
        diagram.AxisX.TimeSpanScaleOptions.GridAlignment = TimeSpanGridAlignment.Hour;
    }             
}

The example uses the following API members:

Member Description
ScaleOptionsBase.ScaleMode Gets or sets the scale mode for an axis.
TimeSpanScaleOptions.MeasureUnit Gets or sets the detail level for time-span values.
ScaleGridOptionsBase.AggregateFunction Gets or sets the value indicating the aggregate function that should be used to relieve data.
ScaleGridOptionsBase.GridSpacing Gets or sets the interval between grid lines and major tickmarks.
